I took the hub apart  it has a spot for a 2nd 90w plug  wired and all jut need to soder in the female   I ordered two more psu s for it to test if they were bad and to use on 2nd jack when I put it on.  can I just add a second plug and psu?  I figured it was an amp issue.. the psu is rated 20v@4.5 amps so I feel that is whats choking me on ports. with anymore on the hub they under prefome/ give the power draw errors ect.. its a power issue..  its personal now between this port and I... its going to hash on 20 ports and like it regardless of what I spend to make that whore hash...
